Subject: linux-next: manual merge of the net tree with the net-current tree

Hi all,

Today's linux-next merge of the net tree got a conflict in
drivers/vhost/net.c between commit
1680e9063ea28099a1efa8ca11cee069cc7a9bc3 ("vhost-net: avoid flush under
lock") from the net-current tree and commit
dd1f4078f0d2de74a308f00a2dffbd550cfba59f ("vhost-net: minor cleanup")
from the net tree.

I fixed it up (see below) and can carry the fix as necessary.
